Superficial Basal cell carcinoma
The basaloid tumor islands in superficial basal cell carcinoma (sBCC) extend from the epidermis into the papillary dermis   . Dermoscopy can predict the diagnosis of sBCC with a sensitivity of 81.9% and specificity of 81.8% .
Features predictive of superficial BCC
1. Leaf-like structures
2. Spoke wheel-like structures
3. Concentric structures/globules (variant of spoke wheel like structures)
4. Brown dots – correspond to small pigmented BCC tumor islands located at the dermal-epidermal junction. Similar size pigmented BCC tumor islands in the papillary dermis appear as blue-gray dots/globules.
5. Short fine superficial telangiectasia
6. Multiple small erosions
7. Shiny white blotches and strands. It is not uncommon for sBCC to only reveal shiny white blotches and strands with or without short fine superficial telangiectasia.
Features predictive against superficial BCC
Features predictive against the diagnosis of sBCC include :
1. arborizing vessels (negative odds ratio 2.1)
2. blue-gray ovoid nest/s (negative odds ratio 3.2)
3. ulceration (negative odds ratio 2.1)
Features that may be seen in sBCC but that are not predictive for or against the diagnosis of sBCC include multiple non-aggregated blue-gray globules and multiple in-focus blue-gray dots, which often present in a buckshot scatter distribution .
Heavily pigmented sBCC can sometimes mimic melanoma . In such lesions the leaf-like or spoke wheel-like structures can resemble streaks (i.e., radial streaming and pseudopods) and the blue-gray globules can take on brown to black colors making it virtually impossible to differentiate these sBCC from melanoma
